1. The problem asks: Which number is 3 units backwards forward from -2? 2. To solve this, we need to understand the number line and the concept of moving units forward or backward. 3. Moving "forward" means adding units, and moving "backward" means subtracting units. 4. Since the problem says "3 units backwards forward," it is ambiguous but likely means moving 3 units forward from -2. 5. The formula for moving forward on the number line is: $$\text{new number} = \text{original number} + \text{units moved forward}$$ 6. Substitute the values: $$\text{new number} = -2 + 3$$ 7. Calculate: $$-2 + 3 = 1$$ 8. Therefore, the number 3 units forward from -2 is 1. If the problem meant 3 units backward from -2, it would be: $$-2 - 3 = -5$$ But based on the wording, the answer is 1.
